Ethereum types, cryptography and utilities.
It is recommended to use the utils, types and abi re-exports instead of
the core module to simplify your imports.
This library provides type definitions for Ethereum's main datatypes along with other utilities for interacting with the Ethereum ecosystem
Signing an ethereum-prefixed message
Signing in Ethereum is done by first prefixing the message with
"\x19Ethereum Signed Message:\n" + message.length, and then signing the hash
of the result.
# async fn foo() -> Result<(), Box<dyn std::error::Error>> {
use ethers::signers::{Signer, LocalWallet};
let message = "Some data";
let wallet = LocalWallet::new(&mut rand::thread_rng());
// Sign the message
let signature = wallet.sign_message(message).await?;
// Recover the signer from the message
let recovered = signature.recover(message)?;
assert_eq!(recovered, wallet.address());
# Ok(())
# }
Utilities
The crate provides utilities for launching local Ethereum testnets by using
ganache-cli via the GanacheBuilder struct.
Features
- ["eip712"] | Provides Eip712 trait for EIP-712 encoding of typed data for derived structs
ABI Encoding and Decoding
This crate re-exports the ethabi crate's functions
under the abi module, as well as the
secp256k1 and rand
crates for convenience.
